The South Bethlehem site of the screening is part of former Steel land, which was at one time considered the largest, private brownfield in the country. Most of the Steel’s operations at the Bethlehem plant closed in 1995; its coke ovens, the final Steel division to close in Bethlehem, went cold in 1998.

The closures left behind a giant swath of unused industrial land, but large portions of it have been redeveloped in the past decade.

The documentary explores the successful transformation of the property, according to executive producer Amy Burkett, who also serves as PBS 39 television station manager.

“This is a pivotal documentary that tells one of the greatest stories of our region,” Burkett said in a statement. “We show how a sleeping giant was transformed into a vibrant community and serves as an economic model for other cities across the country.”

Since 1998, numerous businesses have opened on the property, perhaps the biggest of which is the Sands Casino Resort Bethlehem. The casino opened in 2009 and consistently outperforms other casinos in Pennsylvania in terms of revenue.

In 2011, SteelStacks, an arts and entertainment venue built in the shadows of the preserved Steel blast furnaces, opened. The new PBS 39 studio also is on Steel land. City officials have said they have aspirations of redeveloping other parts of the land for uses including housing.

“Bringing New Life to Old Steel” tells the story of the developments in part through interviews with Bethlehem Mayor John Callahan, Sands Bethlehem President Robert DeSalvio and others.

The documentary, which was produced by the same team that produced an earlier documentary called “Bethlehem Steel: The People Who Built America,” is expected to first air on PBS 39 in January, although the station has not released an exact date and time.
